Introduction

To provide the PCSC Interface on the Android device, additional to the SmartCard API, we implemented a smartcard reader driver (ifdhandler) for PCSC-Lite, which routes the APDU communication through a SmartCard system service to the SmartCard API. PCSC Support for the SmartCard API is an optional component which is typically not required, as the SmartCard API already allow to communicate with any Secure Element. But the PCSC-Interface is the standard interface used for many PC applications accessing smartcards. So this implementation will provide the PCSC interface for already existing native applications (e.g. OpenSC), which are ported to Android and requiring the PCSC interface. Whenever possible, it is recommended to directly use the SmartCard API.

Apply the patches

The patch for PC/SC support on the android device is only required for (native) Android applications relying on the PC/SC interface.

$ cd <ANDROID_SRC_ROOT_DIR>
$ patch -p1 < <path_to_my_patches>/pcsc_systemservice_v098.patch

Apart from adding the PC/SC support, building the Android platform is according to the description in Building the System

Details

The current version of the ifdhandler is a prototype, which allow to route the APDU communication from the PCSC interface to the SmartCard API.
